📝 Provide a clear and concise description of the issue.

After months of running smoothly with default settings, the LXC container's npm suddenly stopped working properly. The Web UI showed "internal error" for any attempted changes.

Long story short, it turned out to be a storage issue. The default storage limit of 4GB was full due to oversized log folders.

The du command returned:

...
769M    /var
341M   /root
1.6G    /data
...
1.6G    /data/logs
...
399M    /var/log
...
1.1G /data/logs/proxy-host-8_access.log

Root cause:

checking the logrotate configuration /etc/logrotate.d/nginx-proxy-manager:

cat /etc/logrotate.d/nginx-proxy-manager

/data/logs/*_access.log /data/logs/*/access.log {
    su npm npm
    create 0644
    weekly
    rotate 4
    missingok
    notifempty
    compress
    sharedscripts
    postrotate
    /bin/kill -USR1 `cat /run/nginx.pid 2>/dev/null` 2>/dev/null || true
    endscript
}

/data/logs/*_error.log /data/logs/*/error.log {
    su npm npm
    create 0644
    weekly
    rotate 10
    missingok
    notifempty
    compress
    sharedscripts
    postrotate
    /bin/kill -USR1 `cat /run/nginx.pid 2>/dev/null` 2>/dev/null || true
    endscript

Please note that the user npm does not exist in the LXC. Instead nginx runs as root.

FIX:

I suggest changing /etc/logrotate.d/nginx-proxy-manager to this:

/data/logs/*_access.log /data/logs/*/access.log {
    create 0644 root root
    weekly
    rotate 4
    missingok
    notifempty
    compress
    maxsize 100M
    maxage 365
    dateext
    sharedscripts
    postrotate
    /bin/kill -USR1 `cat /run/nginx.pid 2>/dev/null` 2>/dev/null || true
    endscript
}

/data/logs/*_error.log /data/logs/*/error.log {
    create 0644 root root
    weekly
    rotate 10
    missingok
    notifempty
    compress
    maxsize 50M
    maxage 365
    dateext
    sharedscripts
    postrotate
    /bin/kill -USR1 `cat /run/nginx.pid 2>/dev/null` 2>/dev/null || true
    endscript
}

Then run logrotate -v -f /etc/logrotate.d/nginx-proxy-manager
Optional for testing, run first logrotate -d /etc/logrotate.d/nginx-proxy-manager, to see what will happen.

The final result:
23M /data/logs

🔄 Steps to reproduce the issue.

1. Install Nginx Proxy Manager with the command bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/nginxproxymanager.sh)" and use default settings.
2. Test the configuration (dry run): logrotate -d /etc/logrotate.d/nginx-proxy-manager
3. Alternatively, check the content of /etc/logrotate.d/nginx-proxy-manager.

❌ Paste the full error output (if available).

logrotate -d /etc/logrotate.d/nginx-proxy-manager returns:

Not an Script Issue. Report this to NPM. Its an Build-In Addon and not from us.

By the way, idk if anyone updates npm anymore. Not an really respond since month in this project
